ORCHARD-HEATING DEVICE.

Application filed February 15, 1909.

To all whom it may concern:

Be it known that I, FREDERICK S'rArr, a citizen of the United States,residing in the city and county of Denver and State of C(llOlllt'lO,have invented certain new and useful Improvements in Orchard-HeatingDevices; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in devices for heating orchards, orother localities, where vegetation is liable to be injured by frost inthe absence of artificial heating protection. ,7

It is well known that in many sections of the country orchards and othervegetation are liable to be injured by frost. to such an extent as topractically ruin the crop.

The object of my present invention is to make it practicable, atcomparatively small expense, to raise the temperature of such localitiesduring the frost period, to such an extent as to prevent injury to thefruit or other vegetation from the aforesaid cause.

My further object is to provide a device which shall be exceedinglysimple in construction, economical in cost, reliable, durable andefficient in use, and to these ends the invention consists of thefeatures hereinafter described and claimed, all of which will be fullyunderstood by reference to the accom-, panying drawing, in which isillustrated an embodiment thereof.

In this drawing, Figure 1 is an elevation of my improved orchard heatingdevice, the upper portion being shown in section. Fig. 2 is a top planview of the same. Fig. 3 is a vertical section of the device taken onthe line 33 Fig. 2, the bar, however, through which the said linepasses, being shown in elevation. Fig. i is a perspective view indetail, illustrating a coi'nbincd grate bar and supporting leg,constituting the important feature of my invention, the parts beingshown on a larger scale. Fig. 5 is a detail view, illustrating themanner of forming the body of the fuel receptacle.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the body or fuel receptacle of my improvedorchard Specification of Letters Patent.

heating device. This receptacle is prefer ably composed of sheet metalcut into sec tions of the shape indicated in l 5, and connected b vproperly seaming the same, the sections being arranged as hown in saidligurc. their upper and lower edges being parallel while their (appo iteedges are inclined toward each other from the upper to the lower edgesof the plates. This construction is set forth in in previousapplication. entitled, Heat and olte generators. tiled August 17, 1909.allowed October 2 3. 19-08. t lerial Xe. 448.9435. and need not befurther described in my present application. which relates to the mannerof forming the support for the fuel receptacle in combination with thegrate bars, or fuel support. connected with the bottom of the saidreceptacle.

As shown in the drawing. the fuel receptacle 5 provided at its bottomwith a noun her of members it. of the construction shown in detail inFig. it, and also on a larger scale than in the other views. This memberconstitutes both a grate bar 7, and a supporting leg 8, provided with anoutwardly turned foot 4. Parts 7 and 8 form right angles, orapproximately right angles, with each other. The top of the part 8 andone extremity of the bar 7 are connected by an interposed, verticallydisposed loop 9, formed by bending the member 6 intermediate its extremities down from the top of the leg 8 as shown at 10, and upwardly asshown at 12. Between the parts 10 and 12 a narrow space is left wherebythe member is adapted to be applied to the lower edge of the receptacle5 (see Figs. 1 and 3), whereby the said members may be readily appliedand detached from the fuel receptacle or body of the device.

As shown in the drawing, there are three members 6 applied to the loweredge of the receptacle 5 in such a manner that the legs 8 form thesupport for the fuel receptacle, while the parts 7 form the grate in thelower part of the receptacle upon which the fuel 13 is supported. Thecombined legs and grate bars are suitably disposed, the bar members 7crossing each other in the central part of the bottom of the receptacleas indicated in Fig. 2. The free extremities of the grate bar members 7are preferably slightly turned outwardly, as shown at 14, whereby theyrest against the inner wall of the fuel receptacle. As the latter islarger 4 the same time supporting at the top than at the bottom andtapers from its upper extremity inwardly, the bars 7 will support thefuel, since, as the latter hasa tendency to press them outwardly, theyengage the inner wall of the receptacle more closely, whereby they areprevented from slipping out at the bottom of the receptacle. By virtueof this construction and arrange ment, these bars form an effectualsupport for the fuel within the receptacle 5.

l-laving thus described my invention, what I claim is:

1. An orchard heating device consisting of a fuel receptacle composed ofan open ended body portion and a plurality of devices removabl connectedwith the lower edge of the body member and forming at legs and gratebars, the grate bars extending at right-angles from the supporting legsentirely across the opening in the body member and having their freeextremities turned upwardly to form means for engaging the inner surfaceof the receptacle, tl c said members being spaced to give a stablesupport to the fuel receptacle, whereby the grate bar portions cross oneanother in the central portion of the receptacle, substantially asdescribed.

The combination in an orchard heating device of an open ended bodymember and a number of members removabl applied to the lower edge of thebody member, the removable members having parts bent to occupy positionsapproximately at right angles to each other, one partof each member forming a support for the fuel receptacle while the other part extendsentirely across the opening in the body member and having its extremitycurved upwardly to form means for engaging the inner surface of the bodymember, the said part constituting a grate bar, the said device having arelatively deep bend or loop adapted to engage the lower edge of thefuel receptacle, substantially as described.

3. A device of the class described comprising a fuel receptacle and anumber of removable members, each of said members being bentintermediate its ends to form a leg and a fuel support, said member alsobeing formed at the angle thereof to removabl} engage the lower edge ofsaid receptacle at one sioe thereof, the free end of the said fuel.support loosely engaging the opposite side of said receptacle,substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
